Diode Coherent can anyone explain me total internal reflection ?
can anyone explain me total internal reflection ???
what is mirage??
explanation of formation of rainbow???
why photo-diode is reverse biased??
why do we need coherent sources for interference??
what are the 2 conditions for sustained interference of light??
please anyone answer all possible questions who ever knows it..THANKSX!!!
total internal reflection is the phenomenon in which if the light ray is incident on a refractory surface (onto the surface of a rarer medium) with an angle more than the critical angle of that pair of media the the ray undergoes reflection following laws of reflection
It is used in optical fibre transmission
Mirage is a natural application of total internal reflection .On a very hot day the air becomes less denser and hence light rays passing through them produce an effect on the receptor of our eye such that a deceptive image is formed
During rain when sunlight ( white light having many wavelengths ) passes through a rain drop it undergoes dispersion through the rain drop and splits into its component colors creating a rainbow
For interference we need two coherent sources because there should be constant phase difference between the two interfering waves since interference is a phenomenon of redistribution of energy it is more dominantly seen if the phase difference between the waves is constant
Two conditions for sustained interference of light is monochromatic wavelength and coherence
High Quality Content by WIKIPEDIA articles Coherent duality in mathematics refers to a number of generalisations of Serre duality, applying to coherent sheaves, in algebraic geometry and complex manifold theory, as well as some aspects of commutative algebra that are part of the local theory. The historical roots of the theory lie in the idea of the adjoint linear system of a linear system of divisors in classical algebraic geometry. This was reexpressed, with the advent of sheaf theory, in a way that made an analogy with Poincare duality more apparent. Then according to a general principle, Grothendiecks relative point of view, the theory of JeanPierre Serre was extended to a proper morphism; Serre duality was recovered as the case of the morphism of a nonsingular projective variety (or complete variety) to a point. The resulting theory is now sometimes called SerreGrothendieckVerdier duality, and is a basic tool in algebraic geometry. A treatment of this theory, Residues and Duality (1966) by Robin Hartshorne, became an accessible reference. One concrete spinoff was the Grothendieck residue.

High Quality Content by WIKIPEDIA articles The Coherent operating system was a Version 7 Unix clone by the nowdefunct Mark Williams Company, originally produced for the PDP11 in 1980. A port was introduced in 1983 as the first Unixlike system for IBM PC compatible computers. Coherent was able to run on most Intelbased PCs with Intel 8088, 286, 386, and 486 processors. Coherent version 3 for Intelbased PCs required at least a 286, Coherent version 4 for Intelbased PCs required at least a 386. Like a true Unix, Coherent was able to multitask and support multiple users. From version 4 on Coherent also had support for X11 and MGR windowing systems.

MPSK (Mary Phase Shift Keying) modulation is used in a wide variety of communications systems. Use of MPSK is widespread in wireless networking standards, telephony links, cellular telephony, digital television standards, fiberoptic communications, mobile communications, and military communications. Systems which use MPSK can be found worldwide in terrestrial, satellite, and deepspace applications. Despite the ubiquitous use of MPSK, some coherent MPSK receiver structures have evolved very little since the Costas loop was invented in the 1950s. In this groundbreaking book, new structures for use within coherent MPSK receivers are presented. These include carrier lock detectors, carrier phase detectors, and SNR (Signal to Noise Ratio) estimators. The aforementioned structures are thoroughly analyzed and compared to previously available structures and it is shown that they have significant performance advantages and have immediate applications for use in MPSK systems. Therefore, this book is indispensable to any scientist or engineer who is tasked with the research or development of MPSK communications systems.

In Coherent Stress Testing: A Bayesian Approach, industry expert Riccardo Rebonato presents a groundbreaking new approach to this important but often undervalued part of the risk management toolkit. Based on the author`s extensive work, research and presentations in the area, the book fills a gap in quantitative risk management by introducing a new and very intuitively appealing approach to stress testing based on expert judgement and Bayesian networks. It constitutes a radical departure from the traditional statistical methodologies based on Economic Capital or Extreme-Value-Theory approaches. The book is split into four parts. Part I looks at stress testing and at its role in modern risk management. It discusses the distinctions between risk and uncertainty, the different types of probability that are used in risk management today and for which tasks they are best used. Stress testing is positioned as a bridge between the statistical areas where VaR can be effective and the domain of total Keynesian uncertainty. Part II lays down the quantitative foundations for the concepts described in the rest of the book. Part III takes readers through the application of the tools discussed in part II, and introduces two different systematic approaches to obtaining a coherent stress testing output that can satisfy the needs of industry users and regulators. In part IV the author addresses more practical questions such as embedding the suggestions of the book into a viable governance structure.

High Quality Content by WIKIPEDIA articles SCI, for Scalable Coherent Interface, is a highspeed computer bus that supports a variety of topologies, speeds and connection systems. It is used primarily in the highperformance computing market, where it is used to build NUMA computer clusters and other parallel architectures. In this role most systems use high speed networking devices, typically Gigabit Ethernet, but SCI is much lighter in terms of the protocol overhead, and can offer considerably higher performance regardless of the actual link speed.

The approach to probability theory followed in this book (which differs radically from the usual one, based on a measuretheoretic framework) characterizes probability as a linear operator rather than as a measure, and is based on the concept of coherence, which can be framed in the most general view of conditional probability. It is a flexible and unifying tool suited for handling, e.g., partial probability assessments (not requiring that the set of all possible outcomes be endowed with a previously given algebraic structure, such as a Boolean algebra), and conditional independence, in a way that avoids all the inconsistencies related to logical dependence (so that a theory referring to graphical models more general than those usually considered in bayesian networks can be derived). Moreover, it is possible to encompass other approaches to uncertain reasoning, such as fuzziness, possibility functions, and default reasoning. The book is kept selfcontained, provided the reader is familiar with the elementary aspects of propositional calculus, linear algebra, and analysis.
